Welcome to RD Sips,

made in Herefordshire and delivered across the UK

RD SIPs supplies certified structural insulated panels (SIPs) and SIP kits for extensions, annexes, garden rooms and houses across the UK. We’re based in Herefordshire and built the business to make SIPs accessible for smaller jobs—without the long lead times, high costs, or lack of support you often get elsewhere.
From first drawings to delivery, we keep it simple: clear advice, fast turnaround where possible, and quality-controlled panels made to meet UK building regs—so you can build quicker, warmer, and with less hassle.
